3PP anti-corrosion steel pipe
3PP anticorrosive steel pipe is a steel pipe polypropylene anticorrosive coating, which is characterized by good heat resistance.
Most of the large pipeline anti-corrosion in China is 3PE coating, and 3PP and 3PE coating belong to the multi-layer coating system, which consists of the bottom epoxy powder, the intermediate layer binder and the outer PP jacket. The performance of PP is similar to that of PE, and 3PP coating is fully capable of producing 3PP coating with 3PE production line, and no special 3PP coating operation line is required. However, the difference in performance of PP and PE materials, and the performance of 3PP and 3PE coating, can be applied to different environments. The advantages of 3PP coating on certain properties make it possible to play a role in areas where 3PE coatings are not available, so there are many pipeline projects abroad that use 3PP anti-corrosion coatings.
At present, it is mainly foreign products that are related to the environment, for some countries with high environmental temperature, and PP is harder than PE, so as to avoid scratch coating.
